10344 CCD Interface Board is designed to work together with the CCD Control Board (10347), both controlled by the [[10353|10353 processor board]]. This board is built around 16 Megapixel interline Kodak KAI-16000 CCD image sensor.
This board include:
* pin sockets for the KAI-16000 CCD image sensor (to facilitate sensor replacement)
* a pair of pre-amplifiers of the CCD output signals
* high-current amplifiers for CCD vertical phase drivers. These signals are multi-level, they are generated by a DAC on the [[10347|10347 board]] and then amplified on this board.
* fast high-current drivers for horizontal phase signals - the AC component is generated by the switches with regulated input voltage, DC shift is added to it (for some signals - to the high level, for others - to the lower level) by the programmable bias voltage generator
* bias voltage generator is used to provide DC bias for horizontal phase signals and the levels for DC signals required fro CCD operation. It uses multi-channel serial DAC (programmed by the signals generated by the FPGA on the [[10353#10347|10347 board]] and operational amplifiers to provide required output voltage range for each signal.
* substrate (erase) pulse generator provides a high voltage (>40V) pulse to erase pixels before the exposure
Connectors:
* 10344 board has a single 40-pin connector (J5) in the middle of the board that links it to the [[10347|10347 board]]
